CENTRIFUGAL SEPARATOR.

Specification of Letters Patent.

Patented Jul y 27, 1909.

Application filed August 30, 1906. Serial No. 332,618.

To all whom it may concern:

Be it known that I, J osva. Moreen, a citizen ()ity, county of (JerroGordo, State of Iowa, have invented new and useful Improvements inCentrifugal Separators, of which the following is a specification.

The present invention relates to an improvement in centrifugalseparators i or milk and other liquids wherein the liquid is feddownward into the center of a rapidly revolving bowl or container andthe separated constituents are discharged from different outlets at ornear the top of the same. In separators of this class trouble frequentlyarises through the 1" oamingo'l' the blue milk, or otherheavierconstituent, as it leaves the revolving bowl, whereby thiselement of the separated substances is likely to become mlxed with thecream or li rhter element at .the outlet.

It is one object of the present invention to supply means whereby thismixture shall be prevented.

Another object ol the invention is the provision of means for catchingthe loam formed as stated above, under such circumstances that it shallcondense, losing theentrained air, and falling back to be dischargedwith the remainder of the blue milk or other heavy element.

The present invention is illustratedin preferred form in theaccompanying drawings, wherein- Figure 1 is a vertical section ol thegeneral structure ol' a centrifugal separator containing my improvement,Fig. 2 is a top plan View of a removable multiple dam and Fig. 3 is amedian vertical section of the device shown in Fig. 2.

The outer casing 1 is supported by the legs 2 and contains the revoluhlebowl 3, the driving shalt 4 ol' which is supported by suitable bearings5 and G. The worm wheel 7, carricd. by the legs 2 driven in any suitablemanner engages the worm 8 to drive the bowl 3. The top 01 the bowl istapered down to a neck 9 at the top. The full milk, or other unseparatedliquid is fed in at the center through the spout 10 and enters certainwell known guiding means within the bowl 3 which are not shown in thedrawing, as they form no part of thepresentinvention. An exit tube orspout 11 is carried Within the upper tapered'part of the bowl 3, andthrough this the outgoing blue milk or other heavy the revolving bowoutlet for the chamber 16. The whole is sur- }.element is forced intothe lower discharge chamber 12 or passage.- Thls chamber 1s 01 theUnited btates, and a resident. 01 Mason preferably made of sheet metal,and is set on the top 01' the casing 1, having a flange 13 being-alsoprovided with the usual final exit spout 14. The bottom of the lowerchamber so I which snugly fits the top of said casing, and

12 is raised so as to envelop the tapered up per portion ofthebowl 3,and forming a neck 15 surrounding and guiding the lower part of i theneck 9. It is just above this neck 15 that the tube 11 discharges, Theupper dis charge chamber 16 or )assage receives the cream or otherlighter e ement which leaves the bowl at the opening 17. The chamber 16is also preferably made of sheet metal and stands 11 on the chamber 12,having a flange 18 whic snugly fits the top 01 said lower chamber. Thebottom 19 of the chamber 16, which forms the top of the lower chamher,is arched upward and surrounds the inner neck 9, servin as an additionalguide for The spout 20 forms the mounted by the receiving bowl or hopper21 into which the full milk is poured, passing through the spout 10 asaforesaid.

The; construction thus far described is already well known and has beenherein set forth merely to make clear the relation, location andadvantages of my improvement.

As the full "milk leaves the rapidly revolving spout 11, it strikes thearched partition 19 with a considerable impact, due to' the centrifugalforce This forms a certain amount of foam and it has been f0 nd that,under certain circumstances, somw of this foam finds its way up" aroundthe neck 9 and mixes with the cream in th upper chamber 16,. In order topreventtliis and to cause detention of the foam until the bubbles break,I have devised the following construction,

On the bottom of the lower chamber 12 at suitable intervals f provide aseries of dams. While these may be of ditlere'nt forms and sizes, andmay occupy a variety of relative locations, I prefer to use continuousparallel annular dams 22 one, above the other as shown in' Fig. 1,.Under these dams the foam is caught as it tends to rise toward the topof the neck 9, rThe fgamthus cau ht ls detained by thedams until the .bubles break, allowing the liquid to leave by the spout14. i

In the form shown in Fig. 1, the dams are shown integral with theconical bottom of the lpaver chamber, and this construction is withinthe scope of my present invention,

but I prefer to use a separable dam-cap such,

- dams, as 22, and the shape of the whole is such that it fits snuglyover the bottom of the chamber 12, producing the same arrange- 'ment asshown in Fig. 1 and with the effect heretofore explained. The mainadvantage of the modificationshown in Figs. 2 and 3 is found in the factthat the cap can be easily removed for cleaning and replaced when wornout. The construction ofa se arate cap of this kind is easier andcheaper t ran of the form shown in Fig. 1.

It is to be understood that, whether integral with the chamber or madeon a separable cap, the dams may have a variety of from my invention.
